Abstract: ABSTRACT OF THE DISCLOSURE     A system including a sensor and electronic instru-mentation for measuring fission gas pressures inside a pressurized system or device or the like, such as a nuclear fuel rod.  The system is based primarily on what is commonly known as the ] effect which is the dependence of the magnetic permeability of certain magnetic materials upon applied stress, and permits pressure measurements to be made without any mechanical or physical penetration of the fuel cladding or end cap of the fuel rod.  In a preferred embodi-ment  pressure sensing is implemented by locating a sensor made from Villari sensitive material inside the pressurized system.  The pressure places a stress loading on the sensor which in turn produces electrical output signals proportional to the applied stress.  By sensing the initial magnetic permeability of the sensor, the difference between that sensed information and subsequently sensed similar inform-ation can be obtained, thereby providing an indication of any change in system pressure and the degree of such change.          Such measurements can be made sequentially at multiple locations by placing an external electromagnetic search coil adjacent the internal sensor in the pressurized system such that the magnetic field of the search coil penetrates the containment wall of the pressurized system, thus inter-rogating the sensor and providing an appropriate readout which can be calibrated in terms of system pressure,

Abstract: Abstract An article and method for preparing wrap-around closures for cables, pipes, slices, and junctions to effect repair, insulation, water-proofing and the like are described.  The article is a generally rectangular sheet of a plastic material which has the property of shrinking toward its original dimensions when it is heated after having been stretched at elevated temperatures and cooled while in stretched condition.  The sheet has a large central section which has been hot stretched and cooled and two small end sections which have not been stretched.  The wrap-around closure is made by wrapping the sheet loosely around the object to be enclosed and bringing the two end sections together so that one overlays together one or both of the facing surfaces of the end sections is coated with a thin layer of a lower alkyl cyanoacrylate adhesive.  The end sections rapidly and strongly adhere to each other.  The wrap-around sheet is then heated to a temperature in the range about 250-375°F. and the central section of the sheet shrinks back toward its pre-stretch dimension tightly engaging the object about which is is wrapped.

Abstract: ABSTRACT OF THE DISCLOSURE           A rod repair splice having a pair of trough shaped bodies each with a rod embracing arcuate flange at one end thereof. The bodies are diametrically mounted on the rod to be repaired with the respective arcuate flanges thereof disposed at longitud-inally opposite ends of the splice.  Each of the bodies is welded along their opposite longitudinal side edges to the peripheral surface of the rod sections.  Each axial end portion of the bodies includes three distinct camming surfaces which slope from the inner surface of the body adjacent to the rod to be spliced to the outer surface of the body.  The sloping surfaces thereby avoid shoulders which might cause hangup upon axial movement of the repaired rod by camming an axial interference in a radially outward direction out of axial contact with the splice.

Abstract: RETRACTION LOCKING SAFETY BELT RETRACTOR               ABSTRACT OF THE DISCLOSURE A safety belt retractor reel which is automatically locked against belt extraction under emergency conditions or with the withdrawal of a predetermined length of belt is provided with a mechanism for releasing and locking the reel against belt retraction operated in response to respective successive short sequential extraction and retraction of the belt.  The mechanism includes a supplementary ratchet wheel affixed to the reel shaft and a pawl spring biased into engage-ment with the ratchet wheel to lock the reel against belt retraction.  A pair of first and second cam discs are rotatably supported by the shaft and individually slip drive coupled thereto. One of the cam discs functions to releasably retain the pawl in its ratchet disengage position and the other cam disc functions to urge the pawl toward the retainer disc against its spring bias with the belt extraction rotation of the reel.  Transfer of the pawl from either its ratchet engage or disengage position to its opposite position is effected by a predetermined extraction of the belt followed by retraction thereof.

Abstract: Abstract of the Disclosure A system is provided for extinguishing accidental fires in paint spray booths of the type wherein oil is used as the medium for eliminating extraneous paint mist and overspray, said system providing control over both the oil and the medium used for extinguishing the fire. In such a spray booth, oil from a self-contained reservoir located at the bottom of the booth is circulated over a plurality of baffles within the booth. Paint mist is drawn by flow of air into contact with the oil covered baffles, and the paint solids are thereby entrained in the oil and collected in the oil reservoir.          An appropriate fire extinguishing system for such spray booth comprises a plurality of water fog nozzles within the booth that are activated in response to a fire, and which therefore discharge water into the reservoir. Pursuant to the invention, means are provided to control and preserve the oil which is displaced by water accumulating in the oil reservoir, to maximize fire-fighting efficiency, and to discharge excess water from the booth while safely retaining the oil.

Abstract: COMMON CONTROL SIGNALING    EXTRACTION CIRCUIT     Abstract of the Disclosure A signaling extraction circuit utilizes common control circuitry to carry out the signal extraction function for all of a plurality of time multiplexed, digital data groups (digroups), each of which comprises 24 time division multiplexed, PCM encoded channels.  Each digroup uses eight bits for transmitting digital informa-tion for each channel, but the eighth bit (D8) is borrowed for signaling purposes in every sixth frame,.  To identify these signaling digits, signaling framing information is inserted in a digroup bit stream in the framing bit position of every other frame (i.e., the subframes).  A signaling subframe pattern store comprising a shared recirculating memory serves to maintain a continuing real time record of the pattern of the signaling framing information for each digroup, as well as a test digroup.          When a predetermined pattern has been recorded for a digroup (i.e., a zero subframe bit preceded by a string of exactly three ones, or a one subframe bit preceded by a string of exactly three zeros) a signal bit store is enabled to receive the D8 bits of the signaling frame which follows the recording of said predetermined pattern.

Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed is a probe which allows for real-time measurement and stabilization of the magnetic flux of a polyphase motor fed by a voltage of frequency controlled from zero.  A magnetic core of the probe consists of laminations of shape similar in shape to this stator laminations.  On a yoke of the core there is wound a measurement winding.  The probe is embodied in a stack of stator laminations, and its measurement winding is fed by voltage of suitably high frequency.  The impedance of the probe, depends on the magne-tizing magnetomotive force of the motor saturating the yoke of the probe through teeth integral therewith.  Changes of the impedance can be converted into a direct voltage representing the value of magnetic flux of the motor.

Abstract: ABSTRACT OF THE DISCLOSURE            An elevator system including an elevator car to be stopped at a predetermined stopping point from any initial speed below a predetermined maximum value, at a predetermined uniform rate of deceleration.  The uniform rate of deceleration determines the desired speed versus distance-to-go reference pattern, which is initiated at a predetermined fixed distance from the stopping point.  If the car speed is at the maximum value, deceleration will be initiated immediately.  If the car speed is below the maximum value, the car is allowed to continue at the same speed until the car speed and location of the car relative to the stopping point match a point on the reference pattern.  This point is accurately determined via digital feedback and comparison circuits which start the elevator car on the desired deceleration speed pattern with zero error.  When the point on the reference pattern is reached, digital control circuitry including an up-down counter provides an error count for an actuator which controls the deceleration of the car to closely follow the reference pattern.
